Dab tsi yog qhov sib txawv ntawm methylcellulose thiab HPMC?

Methylcellulose (MC) thiab hydroxypropylulose (HOLMC) yog ob qho tib si siv cov khoom noj cellule, siv cov khoom noj thiab cov ntaub ntawv hauv tsev.

Tus qauv tshuaj:
Methylcellulose yog tsim los ntawm methylating cellulose thiab feem ntau muaj cov methyl pawg.
HPMC yog ua raws Methylcellulose thiab ntxiv qhia txog hydroxyprropyl pawg, uas ua rau nws muaj solubility zoo dua thiab viscosity hloov.

Solubility:
Methylcellulose tuaj yeem tsim cov dej colloid hauv dej, tab sis nws solubility yog tsawg.
HPMC yog ntau soluble hauv dej, tshwj xeeb tshaj yog nyob rau hauv dej txias, ua ib txoj kev daws teeb meem pob tshab.

Viscosity cov yam ntxwv:
Methylcellulose muaj viscosity ntau dua thiab haum rau cov ntawv thov uas xav tau kev sib raug zoo.
Lub visccosity ntawm HPMC tuaj yeem tswj tau los ntawm kev kho cov qib ntawm hydroxyprropyl, thiab nws daim ntawv thov ntau yog dav.

Chaw Thov:
Methylcellulose feem ntau siv nyob rau hauv cov zaub mov thickeners, yeeb tshuaj yeeb tshuaj, thiab lwm yam.
HPMC feem ntau siv nyob rau hauv cov ntaub ntawv hauv tsev, tsho loj thiab kev npaj tshuaj, tshwj xeeb thaum yuav tsum tau ua kom zoo nkauj.

Thermal Stability:
HPMC muaj siab thermal ruaj khov thiab tuaj yeem tswj kev ua tau zoo ntawm ntau dua qhov kub.
Methylcellulose yuav txwv tsis pub muaj qhov kub thiab txias, cuam tshuam rau nws txoj haujlwm.

Methylcellulose thiab HPMC sib txawv tseem ceeb hauv cov qauv tshuaj, solubility, thiab chaw thov. Qhov kev xaiv ntawm cov khoom siv uas siv yuav tsum tau txiav txim siab raws cov cai yuav tsum tau ua.
